Compared with prior art, the present invention can change numerical value by human body body temperature after falling asleep night, thereby realize automatically the control of closing down to electric light and other electrical equipment, and the user can arrange the time that intelligent switch enters duty, and then reach saves energy, prolong the purpose of electrical equipment serviceable life and prevention potential safety hazard, it is applicable to family's interior space, and is practical, and reliability is high, easy and simple to handle, low price.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is control system schematic diagram of the present invention;
Fig. 2 is working-flow figure of the present invention.
Embodiment
As shown in Figure 1, by STC89C52 single-chip microcomputer [5] control whole system, keyboard [10] can be used for time and the pattern that intelligent switch enters automatic mode is set as the man-machine interaction input equipment, the electrical work pattern of response opening and closing signal when particularly being in automatic mode.Clock chip [6] is used for the expansion single-chip microcomputer, can make things convenient for the system-computed intelligent switch to enter the time of duty and the time of hand switch pattern.The infrared ray of body surface emission sees through Fei Nier lens [2] and arrives infrared temperature sensor [1], infrared temperature sensor [1] receives infrared radiation, be converted into electric signal, because voltage signal is very faint, so need to realize that with the signal amplification circuit of amplifier [3] voltage signal amplifies, single-chip microcomputer can't Analog signals, need the sampling by analog to digital converter [4], quantize with the process such as coding analog signal conversion to be become digital signal, sending into single-chip microcomputer [5] processes, if temperature is in the body temperature scope or descend and to reach predetermined value, trigger the infrared remote control key, infrarede emitting diode emissioning controling signal in the radiating circuit, phototriode in the receiving circuit on the electrical equipment receives infrared control signal, and comes execution action through the effect formation pulse control executive circuit of amplifying circuit.Simultaneously, liquid crystal display [7] can be used for showing body temperature as the man-machine interaction output device, the information such as work at present state
As shown in Figure 2, according to the function of each interface of single-chip microcomputer and the effect of each circuit, can determine the workflow diagram based on the intelligent switch of human body infrared thermometry.Mentality of designing is initialize routine at first, to move clock display and liquid crystal display subroutine during beginning, the keyboard subroutine is regulated the time and date of clock chip [6] and the mode of operation of intelligent switching control electrical equipment response signal as interrupt service routine, simultaneously can input the time that enters automatic mode, when time value runs to the value of automatic mode setting, then start-up temperature gathers subroutine, the body temperature numerical value that infrared temperature sensor [1] records is sent into amplifier and A/D converter processing, then utilize and judge subroutine judgement validity of data, if Temperature numerical is in the body temperature scope, then single-chip microcomputer [5] is given control signal of output terminal, start infrared transmitter and send the electrical equipment start signal, be communicated to infrared remote receiver and open or enter specific mode of operation with control apparatus, record simultaneously the temperature value that collects for the first time, then utilize time delay subroutine, gathered every five minutes, amplify, the inversion temperature data once, and the difference of calculating real time temperature value and initial value, reach 0.5 ℃ when drop in temperature is poor, single-chip microcomputer [5] is given high level signal of output terminal, trigger the power key control remote appliance of infrared light telechiric device [8] and close or enter specific mode of operation, end temp gathers subroutine simultaneously, when these instructions are carried out, do not affect the operation of clock subroutine and display subroutine.If in the body temperature scope, then system does not regard as invalid data to the temperature data that gathers under the automatic operation mode, return under the init state, rerun the temperature acquisition subroutine.So circulation is carried out, and can realize according to the actual requirements the automatic control to electrical equipment.
The above is explained the course of work of the present utility model to be embodied as example, certainly, the utility model is not limited in above embodiment, according to above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the instructions, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the present utility model.
